How do i fix smoke coming off my car?

White smoke comes from water, blue from burning oil and black from too rich a fuel mixture. If the engine was running before the oil change occurred then perhaps you put in far too much oil. This can force oil past seals and into the combustion chamber resulting in thick smoke. Carefully check the oil level on the dip stick for the correct fill level. If there is too much you must remove the overfill. If oil has entered the combustion chamber the plugs may be fouled. Pull one out and examine it. If it is not gray and clean you must clean them all before the spark will jump the gap and the engine can run. If the engine did not run before there is a great chance , based on white smoke, that water is entering the combustion chamber.

I would put the car on stands and remove the oil plug, after the oil has drained, replace the plug and measure the amount and fill to the correct amount

It sounds like you need a good mechanic to fix your oil leaks. It's probably the valve cover gasket leaking oil on the cylinder head and it's running down on the hot exhaust manifold.

You don't mention what that smell is reminiscent of?

You don't mention the colour of the "smoke" and you didn't say whether the engine is petrol or diesel?

You don't mention whether the road behaviour/performance is normal?

White smoke is almost always steam or in the case of a diesel it could be an unburned fuel mist, grey/black is excess fuel and blue or grey/blue is burning oil.

Some steam is fairly normal until the engine and exhaust system is hot but excessive amounts could be one symptom of head gasket trouble. If the engine is drinking coolant and sending it through the exhaust as steam it will sometimes smell spicy.

Burning oil smells a bit like burned eggs in the frying pan.

If the car hasn't ultra-low sulphur oil and fuel the catalytic converter will convert sulphur traces into hydrogen sulphide - the bad egg gas...

Based on the smoke I would say you need to rebuild the engine.
Could be a leaking head gasket, or other problem.
The milky oil in the filler pipe means there is an excessive amount of moisture or water/coolant in the crankcase.

Sounds like a cracked head, or blowen head gasket.....Check the oil again and see if it has mubb looking stuff on the dip stick....also Check the raditaior and see if there is oil in there it will be spotty...It could also be bad rings alowing the oil to paas by the rings and burn off threw the exauist...


Best of luck to you.

Hi :) What is happening? you say Well when you shut the engine down the oil is hot and it runs by the valve stems because the stem guides are warren out and sits on the piston till you start the engine next time. It take a bit to burn it off then it burns clean till the next time you stop running the engine for any lenght of time.Take it in to the shop and have new valve guides put in it or unbrella seals put on under the valve spring this will stop the oil from leaking past the valve stems. I put a cup of transmission oil/Fluid/Dexron2/3 every time i change my oil to keep my valve seals soft and rubbery and it helps

was transmission fluid poured in oil by mistake is oil over full is it comeing from exhaust pipe if none of theses things fix it have oil changed put stop smoke in or oil treatment

Fix the dipstick funnel so you do not have oil dripping onto the exhaust causing white smoke. Some people delay fixing a bad oil pressure sender by running a thicker grade of oil. Synthetic oil tends to be thinner , from this you get benefits, in this case it probably exposed an oil sender that is in the process of going bad. If you put a new oil pressure sender in the motor(about$10) you should be able to fix the problem with the oil light.

White smoke is caused by water and or antifreeze entering the cylinder...If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.
Good luck..i hope this helps.... please rate me a fixya
